Peugeot 406 coupe hdi, mapped and lowered

[ozonehostile]

Spot whats wrong here



Yep, vacuum operated diaphragm full of oil and leaking air when I tested it.

Can't really say Id look forward to changing another anytime soon with how hard it was to access (very bruised and scratched hand and forearms lol) but all worth the trouble with how it drives now

The diaphragm is attached to a plate on the bottom of the cylinder head with all the egr pipes, air intake, brake lines, master cylinder, bulkhead etc etc in the way


Oh and I smashed the cat internals out the other morning, sounds quite beefy now :p

Job for this week is finding somewhere to subtly mount a boost gauge, as running the high boost map file with no way to monitor whats going on concerns me

[ozonehostile]

The newfound torque has been eating my bottom engine mount to the point where the engine was rocking back and rubbing on the heater matrix pipes, powerflex mount purchased and fitted today, much better now 

[titch]

keep an eye on that Powerflex mount as i had major snags with the red 306 one.

I heard there was problems with them rapidly deteriorating, but from the looks they solved that issue with the metal washers

i wouldn't count on it, i had 3 on the 306 and the two later ones had the big washers.

Oh right, I'll certainly keep an eye on it as I have the car on the ramp several times a month usually haha

[titch]

Yeah i would, they will replace it no problem, but i got fed up with changing it every month, but i might of just been unlucky.

Wallowy suspension was becoming a bit of a problem on faster roads, felt pretty unstable over 70mph so it was time for the ozonehostile running gear treatment:


Mandatory before picture



Got the car on the ramp, wheels off and out with the tin of penetrative oil, front struts off and immediately found one of the issues once the strut top was out




Probably the worst bearing I've ever seen haha. 

Gave the metal spring cups a cleanup with the wire brush and painted, probably little benefit but nice to look at lol 


Swapping dust covers and bumpstops trimmed to the new ride height over to the Bilstein shocks 


Something very satisfying about new suspension parts 



Front end all done 


Rear suspension was a bit of a pain, have to remove the boot lining to get to the top of the shocks and incredibly fiddly to get the rear springs in with such a tight space to try get the spring compressor in but a few minutes of swearing and lever bars they were in 



feels like a proper gt car to drive now, much firmer but still smooth, nice and flat around corners and feels much more stable than it did on the 170k old shocks it was on.

boing!

[ozonehostile]

Springs have settled. Result 

[RetroPug]

Looks gorgeous!

[zx_volcane]

so, now you've worked out all the niggles ...

[ozonehostile]

Aha not quite yet, want to sort out some mint bumpers next and got the rear arb bushes to change as there's still a knock 

[ozonehostile]

New issue, chronic heat soak

So biggest dilemma now, less boost or bigger intercooler :p

[ozonehostile]

All is well with the coupe recently, only hiccup I've had was a broken abs sensor wire causing the dash to light up like an xmas tree driving home one afternoon, the wire had come out of the clip on the hub and was rubbing on the tyre.

Thought it deserved a proper valet since its been so well behaved





Since the remap its being returning a steady 42.2mpg over two full tanks, pretty happy with that considering I was struggling to get more than 20mpg with the leaking diaphragm issue

So it would fek a 306 GTi6 over? As thats the typical bench mark when tuning HDi/XUD's.

Hmm it would be close up to about 80mph but I think the 6 would pull ahead slightly every gear and stay there, coupe has an extra 400kg or so over a 306 

[Matt-Rallye]

I think you havent driven your 6' in too long zakk Unless you have over 200bhp in a dirty derval you shouldnt be anywhere near a healthy gti6, i have proved that enough times

I keep thinking about getting it out again but the next day is always pissing down and cold so decide against it haha 

Gti6>boost evritym

Boosted-GTi6 > GTi6

Why not strap a HX35 to the GTi6?

[7057sam]

Looks soo nice

Nice enough not to have a 306

For the same reason it hasn't got throttle bodies yet, shit job with shit pay

[ozonehostile]

Had a day on the coupe to sort some niggely bits, first up rear anti roll bar bushes and the problems I encountered from the last monkey that bodged them together rather than replacing a £6 Bush 





So that was fun.... 


Then set about the usual ozonehostile rust prevention stuff 

[ozonehostile]

Took the coupe along to pugrun on the weekend since the gti6 wasn't roadworthy, but I certainly enjoyed it! 

Nothing to report problem wise with the rolling armchair, still on the lookout for a crack free pair of bumpers but nothing urgent. Just nice to have something where everything works and drives as it should. 

Picture from the way home (450 miles in total averaging 43mpg) 

[Dum-Dum]

Your car looked good on the A34 on the way home mate. Wish I'd got the camera on slightly quicker.

[ozonehostile]

Haha that's awesome.

Was putting the hammer down at that point to get home before 7 aha

[Grant]

Car was looking good mate. Just sort those brakes out for the love of christ!

Aha definitely, it's getting worse every day to the point where entire streets of people turn to see what the noise is

Need something a bit more resistant to heat than copper grease as it only lasts a couple of weeks lol 

[RetroPug]

Lovely picture!

[Poodle]

Can you still get anti-squeal shims from peugeot for this? Failing that some proper brake grease should help.
